"Last year, I didn't think so at first, and I thought, 'Maybe I'm done,'" the 6-foot-5, 345-pound Kemoeatu recalled. "But then I started working out. I was 415 [pounds], but then I dropped 70 pounds and I started feeling like, 'Man, you know what? I can still do this. I can still play.' But I am playing with a chip on my shoulder. I need to prove that I can still play. If I can stay healthy, I can do another three or four more years."
